[solved] No data on dash board since update

I updated the firmware to 1.18.2.r0 and everything works fine but no data is displayed in the dashboard widgets. The Data page shows that all my signals are being received, just no graphs on the Dashboard. The Configuration page says my activation token has expired. Is that the cause?

From the main table, it seems to me that data you receive from signal might be in the array.
How does your send_signal function look on your device? Are you sure you're sending float dataType from Python code, please?
